Well we're getting somewhere. That has made foreach.hpp compile. I
have to #define BOOST_FOREACH_NO_CONST_RVALUE_DETECTION and a couple of
examples I've tried now work.
I haven't tried the tests (not sure how to run them easily) but this
simple example compiles and runs (albeit with a load of compiler
warnings about passing temporaries in to functions)
BOOST_FOREACH( char ch, "Hello!" )
{
std::cout << ch;
}
std::cout << std::endl;
std::vector<int> v;
BOOST_FOREACH(int& i, v)
{
i *= 2;
std::cout << i << std::endl;
}
The compiler warnings are listed below. You can disable warnings
temporarily on borland by
#ifdef __BORLANDC__
# pragma option push -w-8032
#endif
before the call and
#ifdef __BORLANDC__
# pragma option pop
#endif
After the call. Don't know if you want to mess around with you code to
do this or not.
If i get the tests running, I'll report back with the details.
Cheers
Russell
